CREAM-SKIMMER.

Specification of Letters Patent.

Patented Dec. 3, 1918.

Application filed April 13,1916. Serial No. 90.955.

- s'ive article adapted to be detachably clamped -to a milk bottle .orother container and by a simple manipulation "thereof, quickly draw offthe cream content.

Another object of the invention is to provide a simple and effectiveclamp for va- -"riably positioning the device upon the bottle -or othercontainer, and to "provide for indicating the cream level' externally ofthe bottle or other container.

These and various other features which will appear more particularlyhereinafter are secured in the device of the present invention, theconstruction and operation of which, together with a preferredembodiment thereof, is fully disclosed in the accompanying specificationand drawings, throughout which like reference characters arecorrespondingly applied, and in the drawings,

Figure 1 is an elevation of a device in accordance with my invention inposition for use.

Fig. 2 is apartial elevation of a modification, and

Fig. 3 is a plan section of a preferred form of clamp.

I-have illustrated my device in its application to a milk bottle 1 ofconventional the dotted line 3 and the cream is above this line.

In one form of my invention illustrated in Fig. 1 the means'for drawingoff the cream consists of a glass or other suitable siphon -.tube 4having an upturned flaring intake end 5! Y charge end 6 controlled by asuitable shut-oft 5 adapted to be positio ed within the bottle slightlyabove the milk line 3 and a dis- 7 and adapted to siphon the cream'intoa erably markedwith a. transverse line, indi cated by the arrow '20,Fig. l, to register with the bottom of the cream level inthe container.

T the for of my invention illustratedvin in tube is formed in twosechich are flex bly connected by a suitable rubber or other coupling 4to permit the lower section to be swung upwardly at the coupling instarting the siphoning action.

In both forms, the intake end of the siphon tube is adapted to beadjustably positioned witl'iin the bottle according to the cream level.A preferred construction for so mounting the tube comprises a springclamp disposed for adjustable engagement with the bottle externallythereof and below the mouth. The clamp consists of two appropriatelycurved connected spring jaws 9 adapted to embrace opposite sides 'of thebottle and provided between their ends with oppositely arrangedoverlapping cars 10 through which a rivet or other suitable fastening 11is disposed-to connect the jaws at .thispoint. The jaws are normallyurged site to the fastening 11 thereof are suitable rivets or otherfastenings 14 over which. and between their heads and the j aws 9, thebent ends 15 of a pair of wire or other suitable arms 16 and 17 arehooked. One arm 16 is shorter than the other arm 17. but both arms abovet e clamp. meet and are twisted upon each other, extending as avertically disposed sup ort. The longer arm 17, at a suitab e l eir ht aove the clamp is bent laterally and extends above and transversely tothe mouth of the bottle as a horizontally disposed support which whenthe tube and .clamp are-ass mbled is adapted to be bent into averticallv disposed coil 18 through which one portion of the siphonextends and is clamped. The terminus 19 of the coil is bent verticallyback upon itself providing an operating portion whereby the coil may beopened and closed to grip and release the tube. The shorter arm 16terminates sub *erly adjusted within the bottle, the lower y at thelateral bend of the 1 7 and is twisted over said arm. I

In applying theclamp, the-finger portions 13 thereof are gripped andpressedtoward each other to separate the jaws 9 and permit them to becngagedabout the bottle at the desired point. The free end of the arm 17is then bent around the'tube l to iform 'the coil 18 shown in Fig. 2,whereupon the tube is inserted into the bottle to position the upturnedintake end 5 thereof Within the bottle and the discharge end 6downwardly and externally thereof as shown in. Fig. 1. The

tube is adjusted Vertically in the resilient holder 18, by spreadingopen the coil by means of the finger piece 19, until its intake 5 isdisposed just above the milk level of the bottle, whereupon the coil 18is released and its inherent resiliency causes it to return to clampingposition .to :firmly grip the tube and hold it in position.

The-siphoning action is started before the tube is clamped withinthebottle. This may -con-venientlybe done by-filling the tube .with wa'ter.The shut-off 7 is first opened and the tube inverted and filled withwater from the end'6 until the water runs out. After the tube has beenfilled the shut ofl is closed and the tube inserted into the bottle as"shown in "Fig. 1, -.and-"adi u sted'to position '-'as described aboveThe shut-oil may then be opened to allow the contained water infithetube to drain 01:1". This'starts the siphoning "action and as-soon asall the water-in the '35 tube has drainedout, the l-cream begins "to:floW, whereupon the receptacle '8' is p'laced #under the vdischargefiend 6. to catch the cream. a

In the-form of invention shown in F 1g.- 2,-the"-tubeis clamped in themanner fdescribedbaild the siphoning action started by inverting andfilling the lower section "4 with water while pinching the coupling '4between "the fingers to prevent further passage'of the water. When thetube is prop section is again reversed and the coupling released,permitting the water. to drain ofl? and the cream to be siphoned.

Various other modificationsin the form and construction of my inventionmay-ob- -v1ou'sly be resortedto withinth'e l-irnits'iof the appendedclaims. V
